Good day to everyone present.

I am assembling the fuel system of a SKODA OCTAVIA II 2.0 TDi RS (common-rail CEGA) manufactured in 2010. Can someone explain to me exactly how the hoses connect from/to the UFI fuel filter housing? Attached is a picture. I believe the hoses are connected in the following order (from left to right):

1. Supply from the fuel tank;
2. Return line back to the tank;
3. (disconnected hose) towards the auxiliary fuel pump V393;
4. Return from the engine?

I want to make sure I'm connecting this correctly. Thank you!!!
